There are a couple of things in the book that nay not have been in the documentary.
First there is some discussion of how this ofton helps ashmia. And something I found
verry interesting was his mentioning an old spanish study using older adults and a plan
somewhat like JUDDD. They were not trying to lose weight. So instead of eating there
maintenance calories of 1600 per day they ate 2300 calories on an up day and 900 calories on a down day. Those who did this had a lot fewer deaths and days in the hospital all without losing weight.
